What happened
While on approach, the Rockwell Grand Commander 690C Jetprop 840 was observed traveling from west to east after emerging from cloud cover. Shortly after this observation, witnesses noted the aircraft's nose pitched downward, leading to a near-vertical impact with the ground. The collision and a subsequent fire resulted in the total destruction of the aircraft.
Findings
Investigations into the aircraft's mechanical systems showed no evidence of malfunctions or anomalies. However, several environmental and operational factors were identified. At the time of the accident, the weather was characterized by overcast skies and visibility between three and six miles. Although AIRMETS for instrument meteorological conditions and moderate icing were active for the flight path, and an icing probability chart indicated a 76 percent chance of icing during descent, the specific weather briefing received by the pilot could not be verified due to the lack of a recorded source. Nearby aircraft had reported experiencing light to moderate mixed icing.
Operational data regarding the aircraft's loading also revealed significant discrepancies. The weight and balance records indicated that the aircraft departed 1,000 pounds above its maximum allowable gross weight. At the time of the crash, the aircraft remained 560 pounds over its gross weight limit. Furthermore, the center of gravity was estimated to be at or slightly forward of the manufacturer's design limitations, which is a critical factor in flight stability.
